Do you know for a fact that Bob is on TRT or HRT? Or just assuming?
Just curious.
Bob has always been one to be on the vanguard of physical enhancement. Takes tons of supps a day. And he does speak about anti aging methods which include HRT.
Jack LaLanne claims he isn't on HRT and although he's in amazing shape, he doesn't LOOK as good as Bob. (He's also 10 years older!)
